i would also suggest looking at their finished photobooks. one of my friends chose an up n cming phtogapher duo.the pics posted on the website were amazing. like really blown way by the qualityof the shoot.

then the photobook arrive. It was heavily edited. that the turqoise colour of the wedding theme turned out green. the bride looked heavily made up with make up. And then the close ups looked amateur.

So that's my advice. Dont only look at pics on the website. See their photobook product too.
And insist on the CD so at least u can reprint the photobook later using groupon voucher or something later.
